Back in the old days, we'd just create a 1gb file and leave it on the file system. Run out of space? Delete it and revel in your added disk space. Sort of a poor-man's LVM. :)

That's kind of odd, but I guess it's one way to get some space back.

Mind you, this was back in the SunOS/early Solaris days before LVM, when adding disk space usually meant adding another disk and splicing it into
the filesystem somewhere.

ZFS FTW thesedays IMO. Home Built NAS setup.

ISCSI JOBO, Mounted on target servers. Expand as needed.
Full Mirror of the OS in ZFS, can tollerate full disk loss on any of the volumes, including boot drive.

I thought it was BTRFS...

Still usin' ext4 over here.

Re: Re: Back on Track / Beta Testing RH

BTRFS is interesting, but it's more of a linux oriented file system. I personally run most of my home lab on just bare bones FreeBSD. On that system, ZFS is really nice. Instant snapshots. Disk Mirrors and pools. Basically the same exact functionality as BTRFS, just not.

I may ruffle some feathers here, but In my opiniong - one of the slight issues I have with Linux over freebsd is the lack of seperation between user installed programs, and system programs. I have had many install's of linux break themselves after an update. The problem just doesn't exist for me on FreeBSD, The base system is completely seperate from user installed programs. I can deliberately update the base version, when I want to - while keeping the userland programs always running on the latest version of them. While also pulling in patches for security problems for the base. There's a seperation there that's in my opinion extremely nice to have.

When It comes to file servers. That stability - is essential. Especially when everything else relies on it. If the foundation breaks, the whole stack falls. I've spent many sleepless nights trying to un-bork a linux installation after a failed update. I supose BTRFS helps fix this slight issue now, but when I was using Linux on my fileserver it was not an option. On ZFS - I can basiclaly do a rollback to a previous snapshot - if something screws up. On FreeBSD it's been stable enough that i've never had to. I't's been running now for 5 base versions, without a screw up in the update process. I've never gone that long on linux without having to do a full reinstall.

I absolutely love and use linux too, so don't get me wrong.

Recently I have started trying the declarative system called NixOS... tho, I'm personally finding it a bit too "obscure" in it's documentation, as it seems to me they keep changing how to do things, and I'm back to the problem of having to spend 90% of my time reading the manual trying to figure out WTF is going on, instead of actually geting something done.

Nice. I've heard lots of good things about ZFS, not in a place to use it
(yet). My servers are all running on raid-nothing with a NAS NFS share
for data. I've got 2 backups, one is a file copy of the BBS VM, the
other is a full system backup and VM-level backup (fingers crossed)

Interesting. Yeah, I'm looking at ways to setup tiers of storage.
Some things need to be online all the time - for access - others can be turned off to save power and wear and tear on the disks.
One of the problems with using a single server for the bulk of my storage, is that server has to be on all the time and it's quite loud when it contains all those drives.
So I'm thinking about building a small fanless as possible, NVME storage server, with a couple large "BULK" drives to use as "Hot" Data, then potentially using scripts - wake on lan - etc, to trigger another bulk storage server to come online and accept a backup dump, then turn off.
I'm sure there's multiple ways to do something like that, just have to think about it a bit more, & of course collect the funds to buy the toys.

stuff nowadays uses such little power. you can get the system with the fans. you can leave it on all the time. you don't need to power it down.

I like the idea of NVMes for online storage and louder nearline
storage. There used to be enterprise systems that would groom your
data, moving infrequently accessed data to slower drives, and
ultimately to WORM drives for archival access.

I have 5 2tb drives, and the drive head seeking sounds are driving me
crazy. I should try to justify replacing them with SSD for... (checks IT
excuse list) Increased MTBF, lower thermal footprint and decreased
power consumption.

why would you even have 5 2tb drives in this day and are? is your company cheap?
